Blank making mcc/mm'sm.'ihis first grand division comprises means for continuously advancing a Web of paper and for performing a series of cutting operations on said Web during its continued advance ment. Saidcutting operations comprise the making of cuts in each edge of the web, (I, II) cuts in the mid-portions thereof (III, IV) and finally in severing (V) the completed envelop blank from the leading end of said Web, (see Fig. Means are also provided for removing the small portions of Waste paper out from the edges and midportions of the-web. Said web of paper may be supplied in the usual roll as 31 rotatably mounted on shaft 32 in brackets upstanding from the base of the machine.

Fpivots as 3% in frames '25, 26 for engagement with the roll to "keep the web of paper in proper transverse alinement.

visible by the length of the blank measured The Web of paper is then threaded between a plurality of rolls 35, 36, 37 pivotally mounted in side frames 25, 26, and thence to first cutter cylinder 40 mounted for rotation on shaft 39 supported in sleeve-like boxes ll, 42 inreaching from side frames 25, 26 respectively. The web of paper engages the periphery of said cylinder for about half its circumference and while in said engagement cuts I (Fig. 25) are made in opposite edges thereof. The web then passes to similar. engagement with second cutter cylinder 50 similarly mounted for rotation on shaft 49 supported in sleeve-like boxes 47, 4:8 inreaching from side frames 25, 26 respectively. \Vhile the web is in engagement with second cutter cylinder 50 cuts ll (Fig. 25) are made in opposite of said Web. Cylinders 40 and 50 are relatively timed to make cuts I and II at the desired intervals on the edges of the web. As cutter cylinders 40 and 50 are in all respects similar in construction and operation a description of one will suffice for both. Referring therefore more particularly to cutter cylinder 50 Which is illustrated more in detail than cylinder 40, it will be observed that the circumference of said cutter-cylinder is evenly dion the edge of the web. In the present instance said circumference equals four times a blank length and said cutter cylinder is therefore provided at each end thereof with four sets of cutting means equally spaced circumferentially. The several cutting means at one end are arranged relatively opposite those at the other end of said cylinder so as to make cuts, as I in predetermined relation to each other on opposite the Web. As the set of four one end of cylinder 50 is spect like the setof four cutting means at the other end thereof (except in detail profile of cut) a description. of one set will sutlice for both. Also as each group of the set of four cutting means is in every respect like the other three a deseriptionof one will suffice for all. Referring therefore particularly to cutting means indicated in a general way at 45 (see Figs. 1 3, 4) die 38 having in the present instance a cutting profile corresponding With lower cut II (Fig. 25) is formed in or set into the edge of the periphery of cylinder 50. On shaft 43 is rotatably mounted cutter 44 having aprofile complementary to that of die 38. Said shaft 4.3 is approximately tangent to cylinder 50 and to the face of die 38, and is supported in bearings i6, 46 on the end'of cylinder 50. On one end of cutter shaft 43 is bevel gear 51 driven from bevel gear 52 on the outer end of radial shaft 53 in bearing 54 on the end of cylinder 50. Bevel gear 5:3 on the inner end of said radial shaft I p 53 is driven by fixed gear 56 on the inner end of sleeve like hearing a7 of cylinder shaft 49. Thus when cylinder 50 is rotated,

gear has a planetary relation to' fixed gear 56 and is rotated on its own axis during its revolution about said gear 56. Said rotation of gear 55 is transmitted as described to cutter shaft 43; The relative diameters of the several gears of the train are such that cutter 44: on shaft &3 is caused to make one complete rotation during one rotation of cylinder 50, and'the timing is such that said cutter 44 is caused to coact with its die 38 to make its predetermined cut in the edge of the Web While the web is wrapped about the periphery of the cylinder and to then rotate through said die to permit the free tangential departure of the cut portion of the Web from said cylinder. An annular hood 57 is fixed to the end of cylinder 50 for rotation the1"e\vith, by any convenient means as screws 58 and is proas 60 cut from the edge of the Web. Fixed hood 61 having a circular jointure 62 with rotatable hood 57 has pipe 63 leading therefrom. By suitable means not shown suction may be applied to said pipe 63 and chips or waste as 60 conducted away from the cutting mechanism.

Table 65, having apertures as 64 (Fig. ii

therein at suitable places for the operation upon. the web of various instrumentalities, is provided to assist the progress of the Web in its proper direction. Said table is supported on brackets 78, 7am tie rods 82,

respectively reaching from side frame 25 to side frame 26. 7

that of the web, as already described. Yieldable arm 112 is pivoted about midway its length on stud 94 and its upper end engages spring 115 in socket 116 of bearing bracket 99, whereby its lower end is caused to urge roll 103 to coaction wi' .1 roll 101.

For advancing the leading end of the web While it is being severed from the main por tion of the Web to form a blank, rolls 119, are provided. Upper roll 119 is segmental and is fixed to the inner end of shaft 117 having a bearing in bracket 99. The outer end ofsaid shaftll'? has-gear 118 thereon driven from gear 111 on shaft 93 through intermediate gear 121. Lower roll 120 is fixed to shaft 127 revolubly mounted in the lower end of yieldable arm 122 pivoted at 123 in bracket 99. Said arm urges roll 120 to coaction with roll 119 by means of spring 124 in socket 125 in engagement with the up per end of said arm 122. Gear 126 is fixed to the outer end of shaft 127 for engagementwith gear 118.

Angular transfer me0hanism.-Segmental roll 119 and roll 120 are the last instrumentalities to operate upon the web and the first tooperate upon the severed blank. They are the last instrumentalities whose axes are parallel to the axes of the blank forming means The functions of said rolls are first, to advance the leading end of the web, as already described, during the operation of. the severing means and second, upon the completion of the severing and substantially coincident therewith to deliver the blank to the locating means and the gripping means of the transfer mechanism, thereby performing the first step in the operation of the angular transfer mechanism.

- Receiving cylinder 130 is fixed to shaft 131 having one bearing in sleeve 132- of frame 29 and another bearing in frame 30. Above roll 130 in the free end of arm 133 on shaft- 134: parallel with shaft 131 is shaft 135. Said shaft has fixed thereto for rotation therewith front stop 136 for locating the blank relatively to cylinder130. Shaft has gear 159 fixed to the outer end thereof and is driven from gear 140 on shaft 13% through intermediate gear 141 on stud 142 in arm 133. Arm 133 has ear 129 extending downwardly therefrom and sleeve 132 has arm 128 clamped thereto. Between ear 129 and arm 128 spring 1 13 is efficient tourge arm 133 to cause segmental rolls 137, 138 to coact with receiving cylinder 130. Nuts 14:4;

on spring stud 1 15 are efficient to hold segmentalrolls 137, 138 on arm 133 in proper positions relatively to cylinder 130 (Fig. 11). Said cylinder 130 has three receiving beds as 146 thereon and each is provided with clips as 147, 148 for gripping the blank to the receiving bed. Said cylinder is geared to make one third-of rotation for blank delivered thereto. 0n shaft 135 and adjacent to the hub of front stop 136 is mental roll 138 for coaction with cylinder 130 for assisting the delivery of the blank to said cylinder. On shaft 135 on each. side of said segmental roll 138 are segments 132' and 139 respectively. Segment 137 is fixed to the hub of front stop 136 and segment 139 hasv a hub of its own. Segments 137 and are shorter radially than segmental roll 138 and do not assist in feeding the blank but are efficient to prevent buckling and to smooth the blank out on cylinder 130. Each pair clips'as 147, 148 is mounted on one shaft 119 in said cylinder 130 and. said shaft has an arm as 150 having a roll as 151 for en gagement with'fixed cam 152. Said rolls. as 151, are spring urged to engagement with cam 152.

Folding mechanism.The first step in the process of folding the blank is performed on receiving cylinder 130 and comprises the forming of the end creases V1 (Fig. 2 Creasing rolls 161, 162, for coaction with grooves 153, 154 respectively in receiving cylinder 130 are provided to form said end creases. Creasing rolls 161, 162 are set mental (see Fig. 12)'and each comprises tvdo opposite members, as 161 161 of creaser 161. Said creases are fixed to shaft having hearings in side frames 29, 80. Said shaft turns freely in arm 133 and is geared to make one half a revolution for each passing blank on cylinder 130. Directly below said receiving cylinder 130 is transfer cylinder 156 fixed to shaft 157 having bearings 3.17s?

in sicle'frames 29, 30. Said cylinder is provided with four blank receiving beds there on and a pair of grippers for each bed. Each pair of grippers as 163, 161 is mounted upon one shaft as 158 having an arm as 165 1a" carrying rolll66 for engagement with fixed cam 167 on sleeve 276. Said rolls as 156 urged to engagement with said cam by spring actuated plungers as 168. Said transfer cylinder is efiicient to receive the VH, and two bottom flap folders as 181,

, The driving mechanism for myj improved machine is as follows: Main pulley 301 having 302 fixed to the hub thereof is mounted for free rotation on stud 303 outstanding from frame 26. Power may be applied to said pulley 301 from some suitable source not shown. gear 301 on shaft 4-9 of second cutter cylinder 50, on the oneside and through intermediate gear 305, gear 306 on shaft 39 of first cutter cylinder 40. jG'ear307 on shaft 67 of cutter 66 is driven from main gear spectively. Bevel gear 324 on the near end of shaft 20 (Fig. 3) drives bevel gear 326 on shaft 17 lying lengthwise of the machine Said gear 302 drives I Shaft 801 of cutting mechanism 80 in bearings 18, 19 depending from bridge frame 27. Bevel gear 327 on shaft 17 drives bevel-gear 328 on cutter shaft 93. On the other, end of said shaft 93 gear 329 drives' gear 330 on shaft 15 of roll 104:. Bevel gear 331 on the rear end of transfer shaft 20 Fig. 10) drives bevel gear 332 on the rear end of second transfer shaft 280. Gear 333- on said shaft 280 drives gear 334 on-creaser shaft 134: and said gear 334 drives gear 335 on shaft 131 of receiving cylinder 130. Said gear drivesv gear 336 on shaft 157 of; transfer cylinder 156, and said gear 336 drives, in turn, folding cylindergear 337. on

and gear 340 on shaft 227 of gum roll 221 is driven from gear 339. Creaser roll gear 3&1 on shaft 236'is driven from folding cylinder sham 2 onto the body of the blankQstep VII. The

tiallv folded blank then passes onwardly i folding-bed under bottom flap gumas and then under seal flap glimmer 233, step VIII; said gummers having 'eviously received a suitable supply of 1 from gum dish 2200 by means of rolls :1 and The blank on its folding-bed now passes over and downwardly and is flap folders as 181, 182 then swing up from below the surface of the cylinder, lift the bottom flap and fold it over onto the body of the envelop, step X. Directly thereafter this bottom folded edge is delivered onto one of the beds as. 250 of second transfer cylinder 241 and grippers as 243, 24.4 grip said edge to said bed. Ihe end grippers of the folding-bed thereupon release their hold the now substantially folded envelop, with its unfolded seal flap, gummed side down. in depression as 251 of said transfer cylinder, is carried downwardly around on id cylinder and between ironing rolls, as L, and thence upwardly to one of the beds of deliverycylinder 260 on which it is gripped by grippers, as 266, 267, the rippers of the transfer. cylinder thereupon asing their hold. 'Ihcenvelop is then delivered into the bite of drying belts 264:, 265 which engage the envelops near their ends beyond the exposed gummed portions of the seal flap. The speed of said drying belts is such as to cause the envelops to over lap (Fig. 22) and said belts are of'sufiito :ion of the envelops thereby for the dryf of the gum thereon. The envelop then 234i, 286 which run at a speed materially faster than that of the drying belts. The

I cut away portion of roll 286 causes the succ ire envelops to be taken intermittently irom the drying belts. Said rolls 284, 286 advance the envelop over'roll 285' and over table against stop 353. Thereupon segmental roll 287 rotates in coaction with lower roll 285 and reverses the direction of travel of the leading end of the envelop, thereby causing the envelop to buckle downwardly along itsseal flap crease, assisted when necessary by rod 351, and the fold litlength to provide time during the rehas formed isdelivered to the bite of rolls its 285 the completed envelop is de-.
